Thomas Gordon (1692–1750) was a British writer and Commonwealthmen. He was a Scot who attended the University of Aberdeen.
Along with John Trenchard, he published The Independent Whig, which was a weekly periodical. From 1720 to 1723, Trenchard and Gordon, wrote a series of 144 essays entitled Cato's Letters, condemning corruption and lack of morality within the British political system and warning against tyranny. The essays were published as Essays on Liberty, Civil and Religious, at first in the London Journal and then in the British Journal. These essays became a cornerstone of the Commonwealthmen tradition.
